N2 - The annual global fish production reached a record 178 million tonnes in
2020, which continues to increase. Today, 49% of the total fish is
harvested from aquaculture, which is forecasted to reach 60% of the
total fish produced by 2030. Considering that the wastes of fishing
industries represent up to 75% of the whole organisms, the fish industry
is generating a large amount of waste which is being neglected in most
parts of the world. This negligence can be traced to the ridicule of the
value of this resource as well as the many difficulties related to its
valorisation. In addition, the massive expansion of the aquaculture
industry is generating significant environmental consequences, including
chemical and biological pollution, disease outbreaks that increase the
fish mortality rate, unsustainable feeds, competition for coastal space,
and an increase in the macroalgal blooms due to anthropogenic
stressors, leading to a negative socio-economic and environmental
impact. The establishment of integrated multi-trophic aquaculture (IMTA)
has received increasing attention due to the environmental benefits of
using waste products and transforming them into valuable products. There
is a need to integrate and implement new technologies able to valorise
the waste generated from the fish and aquaculture industry making the
aquaculture sector and the fish industry more sustainable through the
development of a circular economy scheme. This review wants to provide
an overview of several approaches to valorise marine waste (e.g., dead
fish, algae waste from marine and aquaculture, fish waste), by their
transformation into biofuels (biomethane, biohydrogen, biodiesel, green
diesel, bioethanol, or biomethanol) and recovering biomolecules such as
proteins (collagen, fish hydrolysate protein), polysaccharides
(chitosan, chitin, carrageenan, ulvan, alginate, fucoidan, and
laminarin) and biosurfactants.
